After spells at Inter Milan, Chelsea, Napoli and Real Madrid, Benitez was brought in to save Newcastle from relegation in March a year ago. "But that is football, you never know", admitted the 57-year-old.
The former Liverpool striker says that he will always have "fond memories of Rafa Benitez", somebody who he describes as a "great manager". I am really pleased here. "He wishes it all the best, and that's how it should be". His Chelsea team drew 2-2 at Anfield in April 2013, a result overshadowed by Luis Suarez taking a bite out of Branislav Ivanovic's arm.
The Magpies have won their last two league fixtures at home, and they would be looking to take advantage of Reds' bad run of form on Sunday.
While Newcastle saw their three-match winning streak in the Premier League come to an end when they lost 1-0 to Brighton last time out.
The Magpies now sit eighth in the Premier League table on nine points, having gone on a three match winning streak after defeats to Tottenham and Huddersfield.More news: Jane Fonda snaps at Megyn Kelly on plastic surgery question
Betfair are pricing Coutinho to score any time at odds of around 6/4 when Liverpool face their old foes on Tyneside on Sunday evening. Three wins from three matches have last season's Championship champions in comfortable 10th place.
Sports Direct tycoon Ashley has reportedly invited Benitez round for dinner recently in what is seen as a build up to contract talks.
"I haven't had too many chances to go back".
He said: "I don't want to say that (I will go back)". It's black and white, and the fans are the same.
As has been a problem for Liverpool in recent weeks, the Reds were unable to capitalise on their dominant display due to a lack of composure in front of goal. Prior to that moment, and for the remainder of the tilt, Liverpool have dominated and managed to equalize only eight minutes later thanks to excellent Philippe Coutinho, who played a neat one-two with Sadio Mane and convincingly scored. "We'll see what we do with them".
Benitez would relish the chance to show Liverpool what they may still be missing.
